To all 'wlwm 'it may concern:

,Be it known that I, COLIN CAMPBELL MCPHEE, a subject of the King of GreatBritain, residing at 31.Cho medy street, in the vV city of Montreal,l in the district of Montreal,

in the Provinceof Quebec, in the Dominion ofCanada,l have invented certain new and useful Improvementsv in Type-Writing Machines, of which the following is a speci,- ii'cation.

VThis invention relates to improvements in typewriting machines, as described in the present speciiication and illustrated by the accompanying 'drawings that form part of the same.

" The invention consists Aessentially of a frame, a traveling platen supported thereby, aplurality-"of pivoted type bars registering onsaid platen, a plurality of pivoted key 2 0`levers and means connecting'said key levers bars.

an -enlar ed sectional in `pairs and a type bar for operating the latter. o' l The objects of the invention are to reduce "the number of keys thereby simplifying the fingering and increasing the speed of the operator, and to eect a compact and durable construction.

The operation of the ribbon mechanism is very similar to that in all visible typewriting machines, with the'eXception of the key and mechanism, Which it operates, for the changing of the color of the ribbon. In this mechanism the key' 55 may be turned one ,way or the other to bring the pivot pin 51 to one side of the bar 42 or to theother side andl against the shoe 52, as there is a continuous rear spring pressure on the bar 42. The change in the position of the said bar 42 will alter the position of the pintle 57 and consequently of the bar 56 and'of the rods 58 rigid with said bar and extending upwardly to the arm from the spool holding cups 174. This operation will determine the position at which the ribbon frame will be set in relation to the platen and in operation the universal bars through the curved fingers 182 will bring the ribbon frame and consequently the ribbon up to the printing position at each operation of the keys. The key will determine as to which ribbon is'brought to position, as stated.

It will be noticed inthe description of the detailed parts of this machine that anew device for supporting the platen has been adopted, viz t'he toggle arrangement 'of bars with one of said barsl slotted and extending down over a roller, the said bar extending downwardly being attached to the frame of the carriage, while the link forming with said bar the toggle-joint is secured to the frame of the machine.

The Vtype writing machine herein described is, as far as I am aware, a radical departure from any known construction and its sim-' y plicity consists essentially in the operation i though the arrangement of partsfis quite as simple and perhaps more so than any typewriting machine now in use, however, in operating this machine, the fingers need never and should not beremoved from the keys at all `and in a very short time, the alphabet, numerals and other characters can be learned from the combinations of keys, so that great speed may be-attained `with'the minimum of exertion, and besides materially' limiting the wear and tear on the machine through pounding, so common to operators of typewriting machines.

The simplicity of this machine is emphasized in the entire elimination of the customary search for keys indicating the dili'erent characters-,- particularly those not commonly used, then again, the keys controlling the shifting'mechanism are immediately under the thumbs, and also the -keys controlling the line spacing mechanism and the pull against the spring pull of the platen carriage, -re spectively, are in the immediate vicinity of position of the thumbs, whenthe fingers are on the eight keys, in other words,

. all the characters and all the movements of the machine may be controlled without lifting the hands from the keys.` There is practically no limit to the speed of construction, beyond the mechanical arrangement oi" the parts, as the knowledge of the combinations producing the letters, numerals and other characters enables the operator to make ,the type bars register on theplaten as ra idly as the said inechanical arrangement wi l permit them to o so.

A number of parts shown in the drawings and described in this specification are extremelyvaluable to this particular construction of machine, but some of them are appli- `cable in the construction to other typewriting machines, as for instance, the manner of supporting the platen carriage and the shif+ ing mechanism. Further it may be said that many of these parts just mentioned may be changed in the construction of a machine. ollowing the resent invention, for while they are descri ed and claimed in this speciication and are very salient features, yet the operation of two key levers to cause one type bar to register on the platen and the means to the invention, and all subsidiary thereto.
